The Impact of Range-Dependent Sediment Properties on the Acoustic Field in 2-D Shallow Water Environments

Abstract

The goal of this research is to understand the effects of range-dependent sediment properties on the acoustic field in 2-D shallow water environments. This information, in part, is required to solve the statistical inference problem in inhomogeneous shallow water environments. The spatio-temporal variability of the water column needs to be properly accounted for while looking for the effect of range-dependent sediment properties on the acoustic field. The objective of the current work is to create a high-fidelity model of the water column along a single propagation track for the Shallow Water 2006 (SW06) experiment. The water column model will include the propagation of nonlinear internal waves through the environment. The purpose of the water column model is to reduce the mismatch between measured and modeled acoustic data so that range-dependent sediment properties can be investigated.
